All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the instant messaging system based on the websocket protocol, as shown in fig. 1, after the client and the server successfully establish the websocket connection, full duplex communication based on the TCP protocol can be performed between the client and the server, the reliability of the communication completely depends on the reliable transmission mechanism of the TCP protocol, and any party performing the websocket communication cannot obtain the correct feedback information of the message sent by the client, so that the problems that the message reliability is affected by loss, dislocation and the like of the message easily occur during the process of continuously performing information interaction after the connection is established between the two parties of the communication, and therefore, the reliability and consistency of the instant messaging message cannot be ensured in the complex network environment in the instant messaging system based on the websocket protocol.
Fig. 2 shows a communication system including a first communication apparatus 1 as a receiving side and a second communication apparatus 2 as a transmitting side, between which the full duplex communication based on the TCP protocol is possible between the first communication apparatus 1 and the second communication apparatus.
The present invention does not limit the specific form of the data sender, and specifically, the execution main body may be a terminal device, a remote server, etc., as long as it is one of the duplex interactions and is an information sender. Similarly, the specific form of the data receiving party is not limited, and the data receiving party may be a terminal device, a remote server, or the like, as long as it is one of the duplex interactions and is an information receiving end.

In some preferred embodiments, the above method further comprises:
recording the time point of each sending information;
and taking each time point of sending the information as a starting point, and if the confirmation information is not acquired after the set time length, sending the corresponding sending information again.
In this embodiment, if the network or the server side is abnormal and cannot confirm the message quickly and timely, the client side is always in a state of waiting for confirmation of the message, that is, in a message sending state. Therefore, a message timeout timer needs to be constructed, and if a message from the server side is not received within a predetermined time, the transmission is considered to be failed, and conversely, the transmission is considered to be successful.
In some preferred embodiments, the method further comprises:
marking the sending state of each sending message, wherein the sending state comprises the following steps: successful transmission, failed transmission, successful retransmission, failed retransmission, and no transmission.

The following description of the present invention is provided with reference to specific scenarios.
A method for realizing the reliability of instant messaging messages based on websocket comprises the following specific implementation steps:
first step, building a communication framework based on websocket
The method is based on the websocket for communication, so a set of basic communication framework needs to be constructed based on the websocket, the framework should include a basic function of establishing and closing websocket connection, and a heartbeat detection function and an abnormal disconnection reconnection function need to be added, a data communication format is specified to ensure a basic communication environment, and a basic environment guarantee is provided for the increase of a message reliability mechanism.
Second step defines the message unique ID generation mode
The client (data sender) should attach a unique ID to a message before sending the message to identify the uniqueness of the message, the generation mode of the unique ID should be negotiated by the client and the server (data receiver), and the uniqueness of the ID at the client and the server needs to be ensured at the same time, so that a specific message can be uniquely located when operating the message.
Thirdly, setting message overtime timer and message state management mechanism
The message overtime timer is mainly used for recording the message sending time, carrying out operations such as retransmission, labeling and the like on messages which are not confirmed after overtime, avoiding the false appearance that the messages are sent successfully, and is an important means for ensuring the message reliability. Meanwhile, a message state management mechanism is required to be added to record and manage the actual state of the message, and the actual sending state of each message can be conveniently obtained through the message state management mechanism.
Fourth step, establishing message discrimination and response mechanism
At the message server side, the received websocket messages need to be screened, non-actual communication contents such as heartbeat detection information are eliminated, and screening is performed according to a specified data communication format. Aiming at the effective information, the server side needs to carry out processing such as data persistence on the information, and sends a confirmation message with a message ID to the client side after the confirmation message is successfully received, so as to inform the client side of successful message sending.
Fifth step of merging the basic communication framework and the reliability mechanism
After the above parts are built, an additional message confirmation mechanism is added to the basic websocket communication framework, and a complete message sending and confirmation mechanism is built, and the structure of the complete message sending and confirmation mechanism is shown in fig. 5.
It can be known from the above scenario that the present invention designs a message confirmation and feedback mechanism for the content of each communication (except for the communication part for establishing and disconnecting the connection), so that the sender of the message can clearly obtain the actual sending state of the sent message, the sender of the message can further process the sent message, the reliability of message sending is ensured, and the reliable transmission of duplex communication is realized.

the obtaining module 13 obtains the confirmation information, which is sent by the other party and is attached with the identification information, so as to confirm that the corresponding communication information is successfully sent.
It can be understood that, a message confirmation and feedback mechanism is designed for the content of each communication (except for the communication part for establishing and disconnecting the connection), so that the sender of the message can clearly obtain the actual sending state of the sent message, the sender of the message can conveniently further process the sent message, the reliability of message sending is ensured, and the reliable transmission of duplex communication is realized.
